u Bottle-Capping Devices, of which the following is a specification.

This invention relates to bottle capping devices, and has for its object a device that is attachable to a table or other support, simple in construction and cheaply made.

To this and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Figure 1 is a side view of the device in position on a support;

Fig. 2 is a front View;

Fig. 3 is a back view;

Fig. 4 is a plan view;

Fig. 5 is a detail View showing the operation of fixing a cap in place and Fig. 6 is a fragmentary sectional view showing the manner in which the lever supporting plate is secured to the bottle supporting plate.

In position on a table or other suitable support 1, the capping device is clamped between the bottle supporting plate 2 and the bracket 3, the latter being of U shaped form and attached at its ends to the upper ends of posts 4, 4, 0n which the plate 2 slides, and which are threaded at their lower ends for the thumb nuts 5, 5, whereby the device is secured to the table. A U shaped flange 6 on the under side of the table provides at its ends guides 7, 7 for the posts 4, 4. Extending between the posts 4, 4 and supported thereby at 8, 8 and also by the plate 2 to which it is secured by a iiange 92L is a vertical plate 9 on which is pivotally supported at one end, the capping lever 10, as by means of the rod 11 fitted in rolled portions at the upper edge of the plate 9. Carried by the capping lever 10 is the capping die 12 that is formed to compress the cap upon the bottle, and is attached to the lever so that it is in correct capping position when the bottle is held in the'recess 13 in the plate 2 and in the Harige 9EL of the plate 9. This recess is in size adapted to support the bottle by the neck by underlying the shoulder formed by the enlargement below the lip, and the bottle is retained in capping position within this recess by the arm 1 4 that is pivoted to the plate 2 at 15, and recessed at 16 to surround the bottle partly. When closed upon the neck of a bottle, the inner edge 17 of the lever 14 lies against a shoulder 18 on the plate 2 and a lug 19, shown in dotted lines in Fig. 1, enters a recess 20 in the plate 2 for securing the lever 14 in closed position.

In operation, after the device has been clamped to a table or other suitable support, Y

a bottle is suspended within the recess in the plate 2, a cap is placed on it, the locking lever 14 is closed upon it, and the capping lever 10 is depressed until the die 12 comes down on the cap, as shown in Fig. 5, and bends it around the lip of the bottle so that it remains in place. The location of the bottle with reference to the die is established each time by the locking lever 14, and the pivoted attachment of the die to the capping lever 10 permits it to adjust itself to the cap before coming into engagement with it.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a bottle capping machine, the combination with a plate provided with a recess, of a holding lever pivoted to the upper side of the plate to bridge the recess and to project from one edge of the plate, and means mounted on said plate for capping a bottle.

2. In a bottle .capping machine, the combination with a supporting plate, of means for holding a bottle to said plate, two posts movable in said plate, a second plate connecting the posts above the first named plate, a lever pivotally mounted on the second named plate, and a capping die carried by said lever.

3. In a bottle capping machine, the combination with a supporting plate having a portion of its upper surface acting as a clamping surface, of two posts movable on said plate, means mounted on the plate for holding a bottle, a clamping member secured to the posts above the plate, means for moving said posts on the plate to clamp a' support between the clamping member and the top surface of the plate, and suitably mounted bottle capping means for c0- operating with the bottle on the supporting late. p 4. A bottle capping machine comprising a supporting plate having a portion of its Aa capping device carried by said lever to coupper surface acting as a clamping surface, operate with a bottlehelol on the first named means for holding the bottle on the plate, plate, and ay U shaped bracket having its 10 tvvo posts movable on said plate,` a Asecond yends.secured to the posts to move therewith plate secured to the first named plate and and adapted to coperate With the first having portions extending about the posts,V namedplate to clamp a support.
